Set shot shooting performance and visual acuity in basketball.

Area of Science:

• Ophthalmology
• Sports Science
• Human Performance

Background:

• Visual acuity is commonly believed to be crucial for athletic performance.
• The specific impact of reduced visual acuity on basketball shooting accuracy is not well-established.

Purpose of the Study:

• To investigate the relationship between decreasing visual acuity and basketball set shot performance.
• To test the hypothesis that shooting performance monotonically decreases with declining visual acuity.

Main Methods:

• Nineteen subjects performed 25 set shots from a fixed position.
• Visual acuity was systematically reduced using optical defocus to levels of 6/6 (or better), 6/12, 6/24, 6/48, and 6/75.
• Shooting performance was measured by the number of successful baskets made at each acuity level.

Main Results:

• A minor, non-statistically significant decline in shooting performance was observed between 6/6+ and 6/12 acuity.
• Shooting performance remained constant for visual acuities ranging from 6/12 to 6/75.
• No significant reduction in set shot performance was found within the tested range of visual acuity degradation.

Conclusions:

• Optical defocus-induced reductions in visual acuity from 6/6+ to 6/75 do not significantly impair basketball set shot performance.
• The study suggests that visual acuity may be less critical for set shots than commonly assumed, within this range.
• Further research could explore other shooting techniques or different visual demands in sports.
